To all whom t may Vconcern:

Be it known that I, STEWART HAn'rsHonN, a citizen of the United States, and a resident of Short Hills, county of Essex, and State of N ew Jersey, have invented a certain new and useful Shade Roller, of which the following is a specification.

The invention relates to window shade rollers and more particularly to such devices as are composed of a solid cylindrical section or sections, and a tubular sheet metal section or sections whereby the length of the roller may be adjusted, but it is to be understood that the invention is not limited to such use, but may be employed in other situations.

The invention is illustrated in connection with a shade roller of the spring action type, but it is desired to have it understood that the same may be carried out in connection with rollers of other types, and withpcurtain poles or the like.

vThe objects of the invention are to provide cheap and eiicient means'for securing a tubular extension to a solid roller, or a solid cylindrical extension to a tubular roller; to produce a combination wood and metal roller which will have all of the strength `and rigidity of the wooden roller andv all of the advantages of the metal roller; to produce a roller in which the wood and metal elements may be readily assembled, and in which the said elements are locked in position by means of the shade fastening means; to produce a roller in which the amount of wood will be reduced to a minimum and in which waste in boring and turning will be eliminated, and by meansof which the liability of the wooden portion to warp will be reduced whereby partly seasoned, and, therefore, cheaper wood may be employed.

These and further objects will more fully jappear in the following specification and accompanying drawings considered together or. separately.

`One embodiment of the invention is illustrated in the accompanying drawings in which like parts in all of the several iigures are designated by corresponding characters of reference, and in which Fig. l is an eleva-tion of a shade roller embodying the invention, the shade being omitted.` Y

Serial No. 680,067.

in Fig. et is shown a roller, the majory portion of which is of tubular metal and which may have a wooden extension at each end. g t

Fig. 5 shows a roller comprisinga plurality of wooden sections alternating with metallic sections.

ln Figs. l, 2 and 3 the body of the roller comprises a wooden element l of cylindrical form. One end of the element is bored to form a socket 2 in which the inner end of a rod 3 is supported, and said rod carries the usual winding spring 4l.

Each end of the element is provided with a kerf 5, or a series of intersecting kerfs cut longitudinally of the element. The lerfs are of a width sufficient to permit the diameterof the element to be reduced at the ends thereof by moving the tongues between the lierfs toward each other, because of the flexibility of the tongues.

Each end of the element is inserted in a tubular, metallic member 6 or 7, as the case may be. The members are closed at the outer ends thereof and theclosed end may carry the usual pint-les, spears, etc.

The diameter of the element l is the same as the outside diameters of the members 6 and 7, but because of the lierfs the ends of the element may be inserted into the bores of the members and be maintained in position by the frietional engagement of the adjusted.

Each member 6 or 7 is provided with a perforation 8 in its wall near the closed end thereof, and when in proper position, the perforations are in alinement In applying a shade to the rol-ler, one end of the shade is laid along the roller and approximately in alinement with the perforations` 8 and covering the same, and is secured in place to the roller by means of strips 9.

The strips are preferably curved laterally to conform to the surface of theroller, and each is provided with a pointed spur 10 projecting longitudinally therefrom but on a different plane from the body of the strip. -The opposite end ofthe strip is provided with an opening through which a nail or tack 11 may be inserted.

The Vspur ispushed through that part of the cloth which covers a perforation 3, the strip is laid' down on the edge of the shade cloth and the strip is pushed toward the closed end of a member 6 or 7, as the case may be. The movement will lock that end of the strip to the member by the engagement of thespur with the interior wall of the member, and lthe cloth will be engaged between the strip and the roller.

v The perforated end of the strip is now tacked to the element by means of a fastening `passing through thev perforation and cloth. The'cloth is now turned'back over the strips and wound upon the roller.

The strips 9 not only serve to secure the shade to the roller between the spurs and the tacks, but the said strips rigidly secure the members to theelements.

If desired, additional strips 12 may be tacked alongv the end of the cloth whereby the cloth will be secured to the roller a practically the entire length of the roller, but

the edge of thecloth will be perforated or cut at infrequent intervals.

That portion of the element 1 between the Amembers 6 and 7 is, with the exception of a short space near each member, of the same diameter as the outside diameters of the members and. the edge of the cloth will be 'supported for practically the entire length of the roller. l

, In theV form of the invention illustrated in Fig. 4 the major portion 13 of the roller is tubular, andmay be provided at each end with a wooden extension 14C whereby the length of the roller may be adjusted.

Near its end the element 13 is provided with a perforation 15 into which the spur may be inserted. The opposite end ofthe strip'mayube nailed directly to the eXtension, but preferably said end rests upon a sheet metal cup 16 into which the end of the extension is inserted, and the nail will pass through the strip, cloth and cap, and into the4 extension whereby the cloth and strip will be secured to the cap and the latter to the wooden extension. The extension is preferably kerfed whereby it will frictionally engage the bore of the element 13.

Figf shows a roller comprising a plurality of relatively short Wooden sections 17 tions engage in the members 6.*andv7 as before` A shade may be secured to the roller and the parts thereof may be secured together as in the form of device shown in Figs.1,2,3and4t. 'f

In accordance with the provisions of the Patent Statutes the principle of the invention has been described, together with the apparatus which is now considered to represent thebest embodiment'thereof, but it is desired to have it understood that the apparatus shown is merely illustrative, and that the invention may be carried other ways.

rEhe invention having been described, what is claimed as new and desired to be secured by Letters Patent, is as follows:

1. A device of the character' described, comprising a tubular member, a cylindrical element adapted to form a continuation of the member, the normal diameter of said element from end toend being greater than the bore of the member, there'being a longitudinal kerf in the element, said kerf eX- tending through the end of the element whereby its diameter may be reduced to permit of the element being inserted in the bore of the member.

out in 2. A device of the character described, V

element adapted to form a continuation of the member, the normal diameter of said element from end to end being greaterr than the bore of the member, there being a plurality of longitudinal kerfs in the element,

said kerfs extending through the end of therelement, whereby its diameter may be reduced to permit of the element being inserted in the bore of the member.

3. A device of the character described, comprising a tubular member, a cylindrical element adapted to forma continuation (of. lthe member, the normal diameter of said element from end to end being greater than the bore olf the member, there being a plurality of lntersecting longitudinal kerfs in the element, said kerfs extending through` the end of the element, Vwhereby its diameter may be reduced to permit of .the element being inserted in the bore of the member.

11. A device'of the character described,

comprising a pair of tubular members, a.

cylindrical element the ends of which are adapted to engage one within each member to form a continuous body, the .normal diameter of said element from end' to end being greater than the bores of the members, there being a longitudinal kerf extending inward from each end of the element whereby thediameters of the ends may be redueed'to permit of said ends being inserted in the bores of the members, said kerfs extending part Way of the length of the element whereby a portion thereoi will be a solid cylinder.

5. A device of the Character described comprising a pair of tubular members, a cylindrical element the ends of which are adapt-ed to engage one Within each member to form a lcontinuous body, the normal diameter of said element from end to end being greater than the bores of the members, there being a plurality of longitudinal kerlisrextending inward from each end oi' the element whereby the diameters of the ends may be reduced to permit of said ends being inserted in the bores of the members, said kerfs extending part way of the length of the element whereby a portion thereof will be a solid cylinder.
